Dear All,
I have a question about the magnetic field of two parallel wires. Here, we got two currents coming out of the page, and the magnetic fluxes flow just like the blue arrow. Usually, in textbooks, they recommend us to find the magnetic field resulting from each current flowing alone first using Ampere's Law, then add them up like vectors co-ordinate-by-co-ordinate.
However, if I let the two currents flow simultaneously and then choose the Amperian loop like the red circle around the current on the left, would the closed-loop integration of the magnetic field along this path equal to this current? If so, what co-ordinate system should I use? Where should I position my origin point?
Best Regards,
